Why Has my Seborrheic Dermatitis Flared After Vbeam? (photo)

I had Vbeam yesterday (my 5th one) and i have these red patches on the sides of my face that have now flared. The rest of my face is not swollen and only minimally red but these patches of seb derm have completely inflamed and I'm wondering if the laser aggrevated them? I always thought vbeam instantly zapped my blemishes and made them look less red, am I wrong?
